self-destructive

The final work of such of this robots, which in times from the old science fiction films come to earth with the aim to conquer they.
Oh, yes. A very logical and sophistical ruling to give this robots a mode of self-destruction. In a more general point of view, self-destructive is not this terrible stupid idea, which seems they. Thus self-destruction preempt the destruction by other guys. This is a advantage if the other people less nice to you than yourself.
